Probably has to do with some type of expired license or its getting re-mastered.
I just finished replaying Alpha Protocol (via CD which I kept).
I enjoyed it when it came out in 2010, but then when Deus Ex Human Revolution came out a year later and did pretty much the same things almost all of them better I decided that I would probably not replay AP. I eventually changed my mind and enjoyed it quite a bit, not to the level of DX:HR but still good in its own right.
I came to both of those later, but also in that order. Very similar games in the ways you describe - I loved both, but Alpha Protocol had a kind of charm that really impressed me. Granted, I think I played it long after the bugs had been addressed, and I approached it like an RPG, rather than an FPS, so the complaints about combat didn't arise for me.
Expired license, unfortunately.
Source? Not sure why Steam wouldn't say that instead of saying "At the request of the publisher, Alpha Protocol™ is no longer available for sale on Steam."
Also they've already asked (last year) on their twitter if people are interested in a remaster "for modern consoles"..

Of course it does not prove that a remaster is in the making though.

I really should give it a try now that I've got a controller. Those mini-games were horrid with mouse/keyboard.
Yep the timed conversations are something no other RPG game has tried yet.
Looks like it's time for another replay for me also.
